A condenser particularly for use in automobile air conditioning system, the condenser including a pair of headers having their inner spaces divided by partitions so as to form a cooling medium flow path in a zigzag patterns including an inlet side group of paths and an outlet side group of paths, side group of paths is 30 to 60% of that of the inlet side group of paths.

A condenser for liquefying gaseous coolant in an air conditioning system of an automobile after the system has compressed the coolant, said condenser comprising: (i) a plurality of flat tubular elements defining flow paths and disposed in a spaced, substantially parallel relation, each element including at least one inside wall; (ii) a plurality of fin members, each fin member disposed between adjacent tubular elements; (iii) a pair of headers disposed in a spaced, substantially parallel relation at opposite ends of the tubular elements, the one and/or the other header defining a coolant inlet and a coolant outlet for the condenser, each header being an elongate member and defining, for each tubular element, an opening through which it receives the tubular element and establishes fluid communication with the element; (iv) at least one partitioning plate mounted in one of the headers transversely of the header to divide the inside opening of the header, said plate including a first portion which extends into a slit in the header and a second portion which is generally co-extensive with the inside opening of the header, said second portion of the partitioning plate being without any perforations; the coolant flowing from the inlet into one header and making a first pass through a plurality of the tubes to the other header, the coolant also making a final pass through a plurality of tubes to the outlet, the tubular elements and headers forming a first zone which receives gaseous coolant from the inlet and a final zone through which the coolant flows before discharging through the outlet, the effective cross sectional area of the flow paths defined by the tubular elements through which the coolant makes the final pass being 30 to 60% of the effective cross sectional area of the flow paths of those through which the coolant makes the first pass; said condenser being able to resist internal pressures greater than 10 atmospheres; each flat tubular element having the following dimensions: width: 6.0 to 20 mm height: 1.5 to 7.0 mm height of each cooling medium flow path: 1.0 mm or more; the fin members having the following dimensions: height: 6.0 to 16 mm fin pitch: 1.6 to 4.0 mm.
